A zero-gravity seat backrest framework disclosed in the invention comprises two backrest side plates which are oppositely arranged left and right, the two backrest side plates are vertically arranged, a backrest upper transverse pipe is connected between the upper ends of the two backrest side plates, and a backrest lower transverse plate is connected between the lower ends of the two backrest side plates; and one backrest side plate is provided with a side plate reinforcing piece, the rear side of the backrest side plate is provided with a guide restraining mechanism used for guiding the safety belt to slide, and the upper end of the backrest side plate is provided with a supporting frame used for reversing of the safety belt. Compared with the prior art, the backrest framework has the beneficial effects that the safety belt guiding and restraining structure and a reversing structure are mounted on the side plate on one side of the backrest, so that large safety belt tension is borne; and the backrest side plate on the side is reinforced, so that the overall strength of the backrest is improved, and the safety of a safety belt system is ensured.

    本发明公开了一种零重力座椅靠背骨架,包括左右相对设置的两块靠背边板,两块所述靠背边板竖向设置,两块所述靠背边板上端之间连接有靠背上横管,两块所述靠背边板下端之间连接有靠背下横板,其中一块所述靠背边板上设置有边板加强件,该靠背边板后侧设置有用于引导安全带滑动的导向约束机构,在该靠背边板上端设置有用于供安全带换向的支撑架。与现有技术相比,本发明的有益效果:靠背一侧边板上安装有安全带导向约束结构和换向结构,因而承担较大的安全带张力,通过对该侧的靠背边板进行加强,提高了靠背整体强度,保证安全带系统的安全性。
